Driver side Door lock probem

Does anyone know why the driver side lock cannot be locked by the FAB ? Ive tried some of the suggestion of getting in the car, starting it, locking it from the inside switch, and then open it get out and then use the FAB, but I cant even get the inside lock switch to engage the driver side lock.

any ideas?

thanks,

No one has had this issue? I'm thinking i have a door lock actuator issue, but the interesting thing is, is that it can be ONLY unlocked by FAB and the interior unlocking/locking button. But no locking of the door can be performed without the physical Key.
any suggestions?

Lock issues were common on early cars. Mine would lock the passenger side all by itself. Problem solved with a warranty repair. Later learned (on 6speed or Pistonheads) that a discharged battery can create all sorts of electrical glitches, including lock problems.

Taught me to use the trickle charger regularly. No recent lock problems, although I did replace my battery this past summer.

P.S. Our batteries weigh 53#.

maybe I should have bought the silver one with the 3 years left on the warranty !
The battery is fully charged and it just seems confused. maybe disconnecting the battery might reset things.
don't know. im thinking the locking mechanism is broken on the locking side, because it unlocks fine.

BTW the FAB is the radio remote control lock gysmo.

anyway, there is nothing I have done to make the remote, or the interior lock button be able to lock the driver side door. UGGGG

Oh, you mean the key "fob". Also, there are known issues with door lock modules that were produced in Spain on early Gaydon cars. AM changed suppliers and there is a service bulletin on how to adapt the newer style modules to the older cars. Dealers still have a supply of the older style modules. If you are not specific in your communication with the service department they will replace your faulty modules with these which means the problem will probably recur in a few years.

Is the module located in the door, as part of the locking mechanism? or is it a control module.

Im getting a service manual which should answer some of my newbee questions.

thanks,

oh yeah, FOB..........

What's the likelihood it's in the lock controller vs at the lock mechanism itself ?
( if there is a lock controller )
Thx

There's a "door module" that looks after locking and window dip when opening. It's inside each door. Mine stopped dipping the driver side window. I unplugged it, waited 30 seconds, and plugged it back in -- the window dropped a bit, I reset the window travel, and all was well for about a week.

Had the module reflashed at the dealer during the last service and it's been fine for months now.

Does your window drop/rise when you open/close the door. Could also be a "door open" sensor that's sticky or shot. Door looks like it's open, won't lock.

Does the latch cycle locked then unlocked when you use the FOB?


Also is there any free play on the inner door handle, or tension throughout it's movement..the free play is a sign of a bent cable that is binding in the cable nylon sleeve..inner handle cables are known to bend and bind, which will cause tension on the latches unlock arm...which will not allow the latch to lock electrically..

Yes, the window does drop and rise upon closing and opening. (the 2-3mm movement)

door open sensor sound interesting to investigate, but then wouldnt the sensor show the light on the dash for door being open? no warning ligthts.

Im thinking of pulling the master power circuit breaker, but there is no "yellow" button on the passenger rear area . just an open hole with something that feels like a button at the bottom. i wonder if this pushbutton fell out somehow. I would hate to push the master breaker and not be able to reset it if the pushbutton switch is broken.

looks like there is the proper tension on that door latch cable. same as passenger side and functional. but, you never know. good thing to investigate.
the FOB doesnt do anything on the driver door as far as locking. unlocking, no problem. the switch by the gear shifter , also , no problem unlocking, but will not lock the driver door, only the passenger door. The ONLY way i can lock the driver door is with the key.

If you get the window drop & rise I think your door open sensor must be working. If you take the door card off you can unplug the door module. That should reset it.

Ok..Drivers door module contorls locking/unlocking. I'm sure your car still has the old style spain modules versus the newer Pektron english modules.

Take off the drivers door panel..the module is that black plastic box on the bottom right of the door..even reads drivers door module on label. I don't remmeber the connector color but check for 2 wires, yellow+black in pin 8 - white+black in pin 21...these 2 wires will be in the same connector..back-pin each pin, close door, lock by remote and see if anything happens..if you get voltage and no action of latch is heard/detected, inspect connector at the latch..same wire colors.

If power present at latch...latch will need to be replaced.

If no voltage at either point, vehicle needs to be scanned with dealers AMDS module is looking suspect to an internal fault...something you can try is, with key on unplug all connectors on drivers door module..turn key off..plug in all connectors from right to left...open and close door, test locking by FOB..still nothing..dealership visit required for module cannot be further diagnosed unless you have access to a AMDS
